Keypress sent to wrong window

[Charles Law]

I have an MDI application which contains a menu, MDI child form and
properties window.

On my Edit menu I have Cut, Copy, Paste, and Delete. The shortcut key for
Delete is set to Del.

In the MDI child form I can select an object and its properties are
displayed in the properties window. All good so far.

If I click in the properties window to edit the properties of my object, I
can type text and use the backspace key, but if I press the Del key to
delete a character, the object is deleted from my MDI child form. This would
seem to be because the code in the menu event handler for Delete calls the
delete method on the MDI child form (which does the delete).

What is the standard way to get the correct behaviour in this scenario? I am
expecting that when the MDI child form has focus then pressing Del will
delete the selected object. But when the properties window has focus I
expect the Del key to work as a normal text editing key.

TIA

Hi Bob

Thanks for the hint. I have looked in MSDN and tried to handle ProcessCmdKey
but my Protected Overrides Function ProcessCmdKey never gets called. Is
there something else I need to do to get it to be called? When it is called,
if I test for the Delete key, how do I get it redirected to the properties
window. Sorry if these are obvious questions, but the fog hasn't quite
cleared yet.

Thanks.

Hmm, This means that by the time you see it the command has already been
handled, by your top-level MDI Parent no doubt.

You could ignore the delete if the property grid has the focus.

You may have to change that shortcut though.

The thing is, I see from all sorts of other apps that they behave correctly
in such a situation. I tried it on the VS IDE and all was well.

It makes me think that there must be a way to deal with this because it must
crop up all the time.

Can anyone suggest a way?
